Introduction: chronic kidney disease (CKD) is characterized by its high prevalence of malnutrition, difficult to detect as it is underestimated by the usual tools. There is no valid or hospital-level nutritional screening tool in Spanish to identify patients with CKD at risk of malnutrition. Objective: to translate and accomplish the transcultural adaptation of Jackson‘s questionnaire (Renal Inpatient Nutrition Screening Tool [Renal iNUT]) to Spanish, which detects the risk of malnutrition in CKD inpatients and compares it with other nutritional tools. Methods: phase 1: translation, back-translation and transcultural adaptation of the questionnaire from the English to the Spanish version. A pilot test was carried out by nursing staff together with a satisfaction questionnaire. Phase 2: comparison of Renal iNUT with Malnutrition Universal Screening Tool (MUST) and Subjective Global Assessment (SGA). Results: phase 1: the nursing staff’s perception was highly favorable. They found it easy or very easy to use and 90 % of them did it in a maximum of ten minutes. Phase 2: from 48 patients included, Renal iNUT detected 44 % at low risk of malnutrition, 28 % at intermediate risk and 28 % at high risk. Increased sensitivity of Renal iNUT (p < 0.007) vs MUST (62.5 vs 33.3 %) and similar specificity (87.1 vs 90.6 %) were found, together with an acceptable correlation compared to SGA (r = 0.75, 95 % CI: 0.67 to 0.83). Conclusions: the Spanish version of Renal iNUT is a useful and easy-to-understand tool for health professionals. We also confirm its good correlation with SGA, with greater sensitivity than MUST for the risk of malnutrition detection in CKD inpatients. [ABSTRACT FROM AUTHOR]

Obesity increases the risk of developing chronic kidney disease (CKD), which has a major negative impact on global health. Bariatric surgery (BS) has demonstrated a substantial improvement of obesity-related comorbidities and thus, it has emerged as a potential therapeutic tool in order to prevent end-stage renal disease. A limited number of publications to date have examined the beneficial effects and risks of BS in patients with non-advanced stages of CKD. We aimed to investigate the safety of BS in patients with CKD stages 3–4 (directly related or not to obesity) and both the metabolic/renal outcomes post-BS. A total of 57 individuals were included (n = 19 for CKD-group; n = 38 for patients with obesity, but normal eGFR [control-group]). Weight loss and obesity comorbidities resolution after BS were similar in both groups. Renal function (eGFR [CKD-EPI]) improved significantly at the 1-year follow-up: Δ10.2 (5.2–14.9) (p < 0.001) for CKD-group and Δ4.0 (−3.9–9.0) mL/min/1.73 m2 (p = 0.043) for controls. Although this improvement tended to decrease in the 5-year follow-up, eGFR remained above its basal value for the CKD-group. Noteworthy, eGFR also improved in those patients who presented CKD not directly attributed to obesity. For patients with CKD, BS appears to be safe and effective regarding weight loss and obesity comorbidities resolution, irrespective of the main cause of CKD (related or not to obesity).

(1) Background and aim: This study aimed to investigate the impact of prehabilitation on the postoperative outcomes of heart transplantation and its cost-effectiveness. (2) Methods: This single-center, ambispective cohort study included forty-six candidates for elective heart transplantation from 2017 to 2021 attending a multimodal prehabilitation program consisting of supervised exercise training, physical activity promotion, nutritional optimization, and psychological support. The postoperative course was compared to a control cohort consisting of patients transplanted from 2014 to 2017 and those contemporaneously not involved in prehabilitation. (3) Results: A significant improvement was observed in preoperative functional capacity (endurance time 281 vs. 728 s, p < 0.001) and quality-of-life (Minnesota score 58 vs. 47, p = 0.046) after the program. No exercise-related events were registered. The prehabilitation cohort showed a lower rate and severity of postoperative complications (comprehensive complication index 37 vs. 31, p = 0.033), lower mechanical ventilation time (37 vs. 20 h, p = 0.032), ICU stay (7 vs. 5 days, p = 0.01), total hospitalization stay (23 vs. 18 days, p = 0.008) and less need for transfer to nursing/rehabilitation facilities after hospital discharge (31% vs. 3%, p = 0.009). A cost-consequence analysis showed that prehabilitation did not increase the total surgical process costs. (4) Conclusions: Multimodal prehabilitation before heart transplantation has benefits on short-term postoperative outcomes potentially attributable to enhancement of physical status, without cost-increasing.

Obesity and kidney transplantation (KTx) are closely related. Obesity increases the risk of chronic kidney disease and can be a relative contraindication for KTx. Besides, KTx recipients are predisposed to obesity and its comorbidities. Consequently, bariatric surgery (BS) emerges as a powerful therapeutic tool either before or after KTx. Since evidence regarding the best approach is still scarce, we aimed to describe renal and metabolic outcomes in a single centre with more than 15-year experience in both surgeries. Methods: A retrospective study including patients who had received a KTx either before or after BS. Usual metabolic and renal outcomes, but also new variables (as renal graft dysfunction) were collected for a minimum follow-up of 1-year post-BS. Results: A total of 11 patients were included: n = 6 (BS-post-KTx) and n = 5 (BS-pre-KTx). One patient was assessed in both groups. No differences in the main outcomes were identified, but BS-post-KTx group tended to gain more weight during the follow-up. The incidence of renal graft dysfunction was comparable (4/6 for BS-post-KTx, 3/5 for BS-pre-KTx) between groups. Conclusions: BS in patients with KTx appears to be safe and effective attending to metabolic and renal outcomes. These results seem irrespective of the time course, except for weight regain, which appears to be a common pattern in the BS-post-KTx group. [ABSTRACT FROM AUTHOR]

Physical activity is associated with a decreased prevalence of obstructive sleep apnea and improved sleep efficiency. Studies on the effects of a comprehensive exercise program in a community setting remain limited. Our objective was to investigate the effects of a combined physical and oropharyngeal exercise program on the apnea-hypopnea index in patients with moderate to severe obstructive sleep apnea. This was a randomized clinical trial where the intervention group followed an eight-week urban-walking program, oropharyngeal exercises, and diet and sleep recommendations. The control group followed diet and sleep recommendations. A total of 33 patients were enrolled and randomized and, finally, 27 patients were included in the study (IG, 14; CG, 13) Obstructive sleep apnea patients were analyzed with a median age of 67 (52–74) and median apnea-hypopnea index of 32 events/h (25–41). The apnea-hypopnea index did not differ between groups pre- and post-intervention. However, in intervention patients younger than 60 (n = 6) a reduction of the apnea-hypopnea index from 29.5 (21.8–48.3) to 15.5 (11–34) events/h (p = 0.028) was observed. While a comprehensive multimodal program does not modify the apnea-hypopnea index, it could reduce body weight and increase the walking distance of patients with moderate to severe obstructive sleep apnea. Patients younger than 60 may also present a decreased apnea-hypopnea index after intervention. [ABSTRACT FROM AUTHOR]
